Vaio VGN-fs980 wireless problem

Hi,

I have a Sony Vaio VGN-fs980 laptop, and this morning when I turned it on, the wireless network connection no longer showed either in the tray or the control panel list of network connections. It WAS still in device manager, but there was a yellow Exclamation point on the picture, and it says it may have a corrrupted driver (code 39). The wireless adapter is the intel PRO/Wireless 2200bg. I tried installing the driver from the sony site:
Sony eSupport - VGN-FS980 - Drivers & Software but nothing improved. Then I tried replacing the actual card with an identical model from another Vaio I had lying around. No go. I tried uninstalling the device drivers from the device manager, then installing the driver, and in the middle of where it says 'installing software; this may take a few minutes', I get this error:

ERROR - The version of the [iprodata\mdriver.msi] MSI is not compatible with FamilyCode version in the INI file.

The same thing happens after a reboot.
Any ideas?

 

Thank you for the reply, however, as I explained, I have tried to reinstall the drivers several times, but I now get an error when I do. One other thing I have discovered is that when booting in safe mode, the wireless network connection still does not show in the list of connections, but during bootup into safe mode, while all the .sys files are loading, I get a message that says "press enter to continue loading sptd.sys". This leads me to believe that there may be something wrong with that file. I don't know if this has anything to do with the wireless problems, but It didn't used to say that.

 

Anyone? it is kind of a pain to have to move to a desk with an ethernet cable every time I want to go online. I have no idea what might be the problem.
